    Object to represent a device mesh. This object is a rough wrapper; it is not guarunteed to be up to date with the state on the server, for instance.

    Args:
        meshid (str): id of the device mesh on the server
        session (~meshctrl.session.Session): Parent session used to run commands
        created_at (datetime.Datetime|int): Time at which mesh mas created. Also accepted as creation.
        name (str|None): Mesh name as it is shown on the meshcentral server
        description (str|None): Mesh description as it is shown on the meshcentral server. Also accepted as desc.
        meshtype (~meshctrl.constants.MeshType|None): Type of mesh this device is connected to. Also accepted as mtype.
